or Armour-E, ONTARIO, CANADA VAPORIZEB Application filed March 20, 1930. Serial No. 437,520.

jected to heat and a means whereby a circulation of air through the chamber may be obtained whereby the fumes from the heated pharmaceutical or other prepartions may be emitted at a pre-determined place( A further object of my invention is to provide a supporting structure for the chamber, which will normally retain the same above a heating medium but which will permit the chamber to be swung around so as to facilitate access to the heating medium.

A further object is to provide supporting members in connection with a vaporizing chamber, which supporting members are supported on a supporting frame in which a heating medium is retained or the chamber, with its associate supporting members, may be placed upon the upper end of a lamp chimney or on the flat surface of a stove or any other similar heating medium.

With the foregoing and other objects in view as will appear as the description proceeds, the invention consists of the novel construction, combination and arrangement of co-operating elements as hereinafter more specifically .set forth, claimed and shown in the accompanying drawings forming a part of the present application in which:

Fig. 1 is an elevation view of the preferred embodiment of my invention. 6

Fig. 2 illustrates the chamber, showing how it may be conveniently supported on the upper end of a lamp chimney.

Fig. 3 is a section view of a lamp chimney showing one of the tension rods in position to retain the vaporizing chamber in position.

Like numerals of reference designate corresponding parts throughout the differentviews.

3 indicates an oil lamp, the bowl of which,

Each of the uprights are provided with'a socket 9, and 11 respectively at their upper ends, the purpose of which will be hereinafter mentioned. 12 is a brace, preferably of annular formation, supporting the upper ends of the upright members 6, 7 and 8 in proper spaced relationship.

14 is a vaporizing chamber having a lid 15 through which the ends of the nipples 16 and 17 extend and are supported in any desired Y air-tight manner. This chamber is for holding any pharmaceutical or other preparation which is to be vaporized. Attached in'any desired manner to the bottom of the chamber 14:, I provide legs 18, 19 and 20. Prefer- 5 ably, these legs are made from 1 wire having a downwardly projecting shank portion and an inwardly extended portion which is looped back under itself. The downwardly projecting portions of the legs are designed to fit into their respective sockets 9, 10 and 11, the legs being in corresponding spaced relationship to the uprights 6, 7 and. 8. The downwardly projecting portion of the leg 18 with the socket 9 willprovide a pivotal connection in which &5

the container 14 may be pivoted to the position as shown in dottedlines Fig. 1, when it is desired to facilitate access to the lamp 3.

The downwardly formed slots inthe sides of the sockets 10 and 11 are so formed as to permit the downwardly projecting portions of the legs 19 and 20 respectively to be swung into snap engagement with the sockets 10 and 11. j V j The nipple 17 has one end ofthe tube21' connected to its outer end, the other end of the tube being provided with an air compression bulb 22, which when pressed will force air into the chamber 14. 23 is a tube of con venient length, one end of which is attached in communication with the nipple 16, while the other end may be provided with any re- 'm ovable nozzle 24:. The chamber 14: and the base 4 may be provided with any desired means for facilitating'the raising of their respective covers 15 and 5.

With the legs formed and attached to the chamber 1 1 in the manner as hereinbefore described, thechamber may be positioned on the upper end of a lamp chimney as shown in Fig. 2. The portions of the leg which extend inwardly and are turned back under themselves provide a spacing medium between the bottom of the chamber and the upper marginal edge of the lamp chimney on which these portions will rest. The chamber 141- may be placed on the flat surface of a stove top or any other similar heating means and the downwardly projecting portions of the legs 10 18, 19 and 20 will support the same in spaced relationship to such fiat top so that the same will be moderately heated. If desired tension rods 26, having coiled portions 27 intermediate their hooked ends, may be connected at 1 one end to the respective legs 18, 19 and 20 and the lamp burner 28.

In the use of the vaporizer as hereinbefore described it will be found most efficient to use'a complete structure as illustrated in Fig.

do 1. The nozzle 24: may be held close to or inserted into a persons nostrils or mouth and the compression bulb 22 operated to force a circulation of air through the chamber 14 and discharge from the nozzle 25 such air 85 with the fumes of the pharmaceutical or other preparation which is being vaporized from the chamber 14. If desired, the tubes 21 and 23 may both beremoved or the cover, with its associated attachments, may be removed and 0 the fumes allowed to circulate freely in the room. If desired, the tube 23 may be used andthe fumes inhaled without the necessity "of forced circulation by the compression bulb 22.

. In the disclosure as shown in the annexed drawings and as hereinbefore described, I have shown an oil lamp 3 as a heating medium but I do not wish to be thus limited as various other heating mediums may be employed Q with-equal adaptability to give as efficient resalts and could be retained in combination withtheframe 6'7812 in proper spaced relationship from the chamber 14 with due consideration being given to the heating .a strength of the heating medium used,

The foregoing specification and annexed drawings disclose the preferred embodiment of my invention, but it is to be understood that minor changes may be resorted to in the do commercial adaptation of my invention without departing from the scope. of the invention as hereinafter claimed.

, What I claim as new is:

A vaporizer comprising a vaporizing cham- #5 her; supporting legs carried in spaced relationship by the bottom of said chamber; a supporting base; a heating medium carried by said base; a frame, supported relative to said base in which one of said legs is swivelly supported and the remaining said legs removably and resiliently retained in said frame.

In testimony whereof, I aiiiX my signature.

WELLINGTON SHIPMAN.
